Patented May'20, 1930 ALBERT A. KAMIN, OF CHICAGO, ILLINOIS SCREEN SLIDEApplication filed September 7,1928. Serial No. 304,402. g

This invention relates to an improvement in screen slides, and relatesparticularly to a metallic screen slide adapted to be attached to theblind stop at each side of a window frame, and an object of theinvention is the provision of a metal slide of this nature constructedso as to have no exposed sharp edges, and also provided with improvedmeans for attachment in the form-of slight depressions and partialperforations to permit the convenient penetration of small screws orbrads.

A further object is the provision of an air space between the engagingsides of the screen slide and the'screen adapted to beinserted therein.

Other objects will appear hereinafter.

The present application constitutes a substitute application forapplicants previously filed application Serial No. 120,278, filed July 23, 1926, entitled Window slide.

The invention consists in the combination and arrangement of partshereinafter described and claimed.

The invention will be best understood by reference to the accompanyingdrawings forming a part of this specification, in which:

Fig.1 is a front elevational view of the device of the invention,secured upon each side of a window frame of a type ordinarily used so inframe house construction, with a half screen held in place by theslides;

Fig. 2 is an enlarged section taken upon the line 22 of Fig. 1;

Fig. 3 is a perspective view of the device of the invention secured tothe blind stop of window frame construction such as is ordinarilyemployed in brick buildings;

Fig. 4 is a sectional view of the construction shown in Fig. 3;

Fig. 5 is a perspective view of the upper portion of the screen slide ofthe present invention.

The manner of attachment of the slide of the invention is the samewhether used in connection with the frame type of window casing or thetype used in brick building construction, as in either type the slide ispreferably attached to the blind stop which extends vertically upon eachside of the casing.

As illustrated in the drawings, a pulley stile 8 is disposed upontheside of the window frame and is provided with the usual parting stop9. The'device of the invention, which is adapted to be attached to theblind stop 10 comprisesa rear fiat'portion 11 and side po'r 'tions 12which are preferably angles to the rear portion 11.

C3 bent at right For the purpose of avoiding exposed sharp edges, eachthe parallel lateral pro]ections 12 is preferably bent upon itself toform a bead 13, and as thisbead is preferably inwardly as shown in Fig.5, an air space is provided at thecorner edges of the screen 14:whichfits intothe slide, and this construction facilitates theevaporation of moisture which accumulates in damp or rainy weather,having the o5 effect ofprolonging the life of the wooden screen.
